HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 296,996, dated April15, 1884.

Application filed November 12, 1883.

l splines, which are intended to iit closely in T0 @ZZ whom t mayconcern,.-

Be it' known that I; HoLooM OLsoN, a citizen of the United "States,residing at Mariadahl, in the county of Pottawatomie and State ofKansas, have invented certain new and ,use ful Improvements-inHorseshoes, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to horseshoes; and the object I have in view is toprovide the shoe with heel and toe calks, which may be removed readilywhile the shoe is on the foot of the horse. for the purpose ofsharpening or renewing said calks.

In the accompanying drawings, making a part of this specification,Figure l represents a sectional view of a horses hoof with my improvedshoe secured thereto. Fig. 2 is a front view of the shoe detached. Fig.3 is a sectional view of the heel of the shoe at one side. Fig. 4 is adetached View of a screw that I use in securing the toecalk in place. InFig. 5 I show a perspective of one heel of the shoe and also aperspective of the calk which is to be secured thereto.

In the figures, A represents al horseshoe, formed in any of thewell-known and usual ways upon its upper or inner face. This shoe has aange, B, around its outer edge, on its under side, such as is frequentlyused upon winter shoes, and this ange, together with a small portionofthe body of the shoe, is cut away at the toe, so as to form adovetailed recess to receive a correspondingly shaped tongue, d, uponthe toe-call; D. Thetoe-calk.)l

has an extension, c, rearward, which lies against the under side of thetoe of the shoe,`

and is secured thereto by means of a screw, E, which has, preferably,cross-cut slot-s in its head. The outer end of this extension is turnedup and then over the web of the shoe, and thus forms an additionalsafeguard for holding the call; in its place. Two slots, 71. and li, areformed in each of the heels of the shoe, and run longitudinally, onebeing vertical and the other horizontal in position. The horizontals'lot is made at the base of the flange B, so that the bottom of thecalli will have a flat bearing upon the under face of the shoe. Thevertical slot is made in the shoe proper or web of the shoe.

F F represent the heel-calks, which are, of course, sharpened, as usual,for ice, sleet, &c. Upon two sides of these calks are formed (No model.)

the slots in the shoe-heels. The splines are at right angles to eachother, and when they enter the grooves or slots in the ends of the shoeand the calks are driven forward with a hammer a very tight fit iseffected. The calks may be secured in place by means of screws or bypartially closing the ends of the slots by any suitable instrument; butas a general thing they will remain without the aid of such means. Vhenthe horse is traveling forward, the pressure of the calk is forward. Instopping quickly or in backing the reverse is the case; but the curve ofthe shoe makes a diagonal pressure, as seen by the line m x, Fig. 5, sothat the friction caused on the side of the calks and splines,togetherwith that caused by the weight of the horse, being thrown upon thecalks, prevents their backward move-A ment. Vhen a horse either stopssuddenly or backs, his front feet are thrown well forward of, and hishind feet well under, his body, thus throwing his entire weight upon theheel-calks. This weight tends to clamp the calks and to producesufficient friction upon it to keep it in the shoe.

I do not claim, broadly, atoe-calk lying against` the ,web of the shoeand having its rear extension turned up and over said web; but

W'hat ,Ido claim is- 1.A horseshoe having a downwardly-projecting flangeon its under side, and having a dovetailed opening in said flange andpartially in thetoe of the shoe, in combination with a toe-calk vwhichis adapted to t into said opening, and which hasa rear extension whichlies against the web ofthe shoe and turns up and over said web, as andfor the purpose set forth. 2. A horseshoe having a downwardly-projectingflange on its under side, and provided at its heel with a longitudinallateral slot at the base of the flange and a longitudinal vertical slotin the web of the shoe, in combination with the call; having splines ontwo of its sides to tit into said slots, substantially as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
